i have a 1990 supra... its an open bow and direct drive inboard. i have 1 550lb and 2 350lb fat sacs and usually about 4 people in the boat. the only time i used the sacs i had the 550 in the back middle and the 2 350's on the side i surf on..... the wave was not the best so i know i need to move things around. where should i put these fatsacs and the people in my boat to get the best wave?

oh and there is a trim tab on the back i can adjust up or down not sure if that wil help to make a better wake.
